Abstract
This study focused on the biomedical significance of the ethanol bark
extract of Tamarindus indica L. The dried bark was extracted with
ethanol; rotary evaporated and lyophilized which was used for the
evaluations of antioxidant and antimicrobial properties. Antioxidant
activities of bark extract observed using nitric oxide radical scavenging
assay showed a most appreciable value of 87.9%, followed by DPPH
photometric assay which showed the next appreciable activity of
78.89%, moreover hydrogen peroxide scavenging assay revealed
43.8% activity and superoxide radical scavenging assay showed the
least activity of 21.32% among the tested procedures. Further, the
extract also revealed promising antimicrobial activity against three
human pathogens viz., Streptococcus pneumoniae, Escherichia coli
and Salmonella paratyphi. All these observations showed the ethanol bark extract from
Tamarindus indica showed significant properties of antioxidant and antimicrobial activities
which proved to be the excellent sources of applications in the field of biomedicine.
